19 Jun 2009	MATLAB Central Team	LI-TIFROM is a sparsity-based Blind Source Separation method. It is based on a time-frequency (TF) analysis: 1) it first finds single-source TF zones, i.e. a set of adjacent TF windows, where a single source is active. 2) Then, in each of the above zones, it estimates a column of the mixing matrix. 3) When all the columns of the mixing matrix have been estimated, the last step consists in recovering the sources. The LI-TIFROM package is written in MATLAB, needs the MATLAB Signal Processing Toolbox in order to run and has been tested on MATLAB 6.0, 7.0 and 7.5.

LI-TIFROM is a sparsity-based Blind Source Separation method. It is based on a time-frequency (TF) analysis:

1) it first finds single-source TF zones, i.e. a set of adjacent TF windows, where a single source is active.

2) Then, in each of the above zones, it estimates a column of the mixing matrix.

3) When all the columns of the mixing matrix have been estimated, the last step consists in recovering the sources.

The LI-TIFROM package is written in MATLAB, needs the MATLAB Signal Processing Toolbox in order to run and has been tested on MATLAB 6.0, 7.0 and 7.5.
